API600傘齒輪閘閥特點
- 通過閥座氣密性的短程或遠程保護提供關閉。
Positive shutoff with visual or remote proof of seat tightness. - 沒有產品污染的優良氣密性。
No product contamination absolute tightness. - 雙閥座:合成橡膠 -金屬閥座加上金屬-金屬**重密封。
Dual seating.
Elastomer-to-metal seat plus metal-to-metal secondary seal. - 防火:如果**重合成橡膠閥座在火災期間被損壞,則金屬-金屬閥座還可以保證氣密性。
Fire Safe.
The metal-to-metal seat ensures tightness if the secondary elastomer seat is damaged during the fire. - PTFE閥座鑲嵌件:抗介質的腐蝕,在工作溫度達到204°C時,具有很好的抗磨能力。
PTFE seat insert
resists corrosive media, has high abrasion resistance and operates
up to +400°F (204°C). - 配置410不銹鋼和密封焊接的閥座硬面。
Seat hardfaced with SS 410 and seal welded.
易于在線進行閥門閥座維修
EASY IN-LINE VALVE RESEATING
閥座用410不銹鋼進行硬面,通過焊接裝配延長使用壽命。將楔板從閥體上拆卸后,磨損的軟閥座鑲嵌件就很容易更換了。在更換閥座鑲嵌件之前,關閉流體,減輕壓力。
Seats are hardfaced with SS 410 and welded-in for lifetime service. A worn soft seat insert can easily be replaced after removal of wedge from the body. Shut off flow and relieve pressure before replacing the seat insert.
